In particular, the first valve 46 and the second valve 48 different flow housing 102 . 104 on.

According to a further aspect, the valve body 18 also a substantially circumferential groove for receiving the sealing element 68 exhibit. The 3 shows the valve body 18 with mounted sealing element 68 , The sealing element 68 is on the valve body 18 appropriate. The sealing element 68 can in the, in particular completely, circumferential groove of the valve body 18 to be appropriate. The sealing element 68 may be located only partially within the groove in the radial direction.

The valve device, in particular solenoid valve device, comprises at least one valve seat 14 and at least one operating unit 16 that has at least one valve body 18 and at least one actuating element 20 that results in a transmission of an actuating force to the valve body 18 is provided. According to the further aspect, the valve device is characterized in that the valve body 18 having a groove and that a sealing element 68 is disposed at least in part within the groove, wherein the groove has a trapezoidal shape in cross section. The opening, or the width of the groove in the radial direction increases. The groove is trapezoidal in cross section. The groove bottom is substantially parallel to the longitudinal axis of the valve device 10 educated. At least one of the groove walls extends obliquely to the groove bottom. The angle between the groove bottom and groove walls is between 90 degrees and 150 degrees, preferably 100 to 150 degrees. The sealing element 68 is in the assembled state on the groove bottom and the two groove walls. Due to the oblique formation of the groove walls load peaks are lower. The sealing element 68 is not expressed by the oblique formation of the groove walls on the formed on the radially outer end circumferential edge of the valve body 18 from.

According to a further aspect, the groove walls have a part extending obliquely in relation to the groove bottom and radially further outside a part running perpendicular to the groove bottom. The groove walls have an angled portion.

According to another aspect closes to the valve body 18 on at least one of the groove walls, in particular radially outboard, extending parallel to the groove bottom region. Subsequent to the region of the valve body 18 is formed as a truncated cone or as a cone tip. The truncated cone or the cone tip is formed so that this in the valve seat 14 can be introduced. The sealing element 68 is intended to provide a tight fit of the valve body 18 in the valve seat 14 to enable.

The sealing element 68 may be formed in particular as a sealing ring with an elliptical cross-section. For mounting the sealing element 68 this is stretched on.

The other aspects shown above may be with respect to sealing element 68 and the substantially circumferential groove corresponding to all described in the context of this application embodiment of the valve body 18 be transmitted.
